The industry's first VXS Payload Extender Boards for payload or node slots let circuit cards come completely out of a card cage or enclosure so that they can be tested or debugged. This provides access to both sides of the test board. There are test points for all lines on each 160-pin connector and the MultiGig P0 connector. The boards come in a 10-layer stripline design for rigid PCBs and microstrip design for flexcircuit portions. An included ammeter measures current and has a digital indicator on the front panel showing the status.
